looks like you have a rifle length gas system, what buffer and spring did you end up going with? Also you may check the gas block to ensure its lined up with gas port in bbl. If you have a drill index, try to determine the size of your gas port as well, I think it should be around .0935. Its either over gassed or under gassed most likely. One other thing I can think of is faulty magazine, but its seldom that easy. Keep us posted.
